Nonrefillable attachment



March 16, 1937. J. w. SCHIEBER NONREFILLABLE ATTACHMENT Filed Oct. 29, 1956 Patented Mar. 16, 1937 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a non-refillable attachment for bottles, jugs and containers, and is designed. primarily for use in connection with bottles containing high grade liquors, wines, perfumes, etc., but it is to be understood that the attachment, in accordance with this invention,

may beemployed in connection with any type of fcontainer, holding powder or pellets, for which it is found applicable.

The object of the invention is to provide, in a manner'ashereinafter set forth, an attachment of. the class referred to which, when in anchored position with respect to a bottle, will prevent the surreptitious refilling of the bottle after the original contents of the latter have been discharged.

A further object of the invention is to provide, in a manner as hereinafter set forth, an attachment, for the purpose referred to, which will permit a steady discharge, with no surging action, of the contents of a bottle when the latter is tilted from the vertical to beyond the horizontal, and further will prevent discharge from the bottle when the latter is disposed in a vertical inverted position. 7

Further objects of the invention are to provide, in a manner as hereinafter set forth, a non-refillable attachment for bottles, jugs and containers which is simple in its construction and arrangement, readily installed with respect to the neck of a bottle, jug or container, strong, durable, compact, thoroughlyefficient in the use intended thereby and comparatively inexpensive.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as will be hereinafter more specifically described and as are illustratedin the accompanying drawing wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall with- :in the scope of the invention as claimed.

In the drawing:-

Figure 2 is a vertical sectional View of the attachment installed with respect to a bottle,

Figures 3, 4, 5 and 6 are, respectively, sections on lines 33, 4-4, 5-5 and 66, Figure 1,

Figure '7 is a top plan view of the combined valve seat and intake member for the valve chamber,

Figure 8 is a top plan view of the combined sealing and retaining element,

Figure 9 is a longitudinal sectional View of the attachment free of the bottle neck, and

Figure 10 is a modified form of attachment.

With reference to Figures 1 to 6, both inclusive, the attachment is generally indicated at I2 and it includes a hollow body part I3 of cylindrical cross section. The body part l3 has an outer terminal part I 4 of reduced outer diameter with respect to the remaining part I5 thereof The part I4 is tubular, of less length than part I5 and constitutes a neck for receiving a closure [6 in the form of a cork. The part I4 also functions as a discharge outlet for the contents of the bottle I1 and an air intake as indicated at M when the contents of the bottle are being discharged.

The breast and neck of bottle l'l are indicated at l8, l9 respectively. The neck I3 intermediate its ends isformed with an annular stop bead or flange 26 on its outer periphery. That portion of the neck extending outwardly from bead is of reduced thickness, as at 2| and is provided with threads 22 on its outer periphery.

The body part l3 has parts of. different uniform inner diameters as indicated at 23, 24, and 26 and a portion 21 of gradually decreasing diameter outwardly. The part 24 is of greatest inner diameter and it is interposed between parts 23, 25. The latter is of smaller inner diameter than part 23. The part 25 is of greater diameter than part 26. The part 23 is of greater length than parts 24 and 25. The parts 24, 25 are substantially of the same length. The part 26 is of greater length than part 23. The part 21 is of greater length than part 26 and the greatest diameter thereof corresponds to the diameter of part 25. The junction of the parts 23, 24, 25 and 26 form the body part 13 with internal annular shoulders 28, 29 and 30.

The part 23 is threaded and is at the inner terminal portion of the part l5 and provides the body part l3 with an internally threaded annular coupler 3| for encompassing and connecting the body part l3 to the reduced portion 2| of the neck l9 of the bottle.

The shoulders 28, 29 coact with the parts 24 toform body part I 3 with an internal annular groove immediately forward of the part 23. The parts 26, 2'! coact to form body part [3 with an internal valve chamber 32 having its rear portion 01 uniform diameter and its forward portion of frusto-conoidal contour. The chamber 32 is closed at its forward end and open at its rear end.

The body part 13 is formed therein with a pair of oppositely disposed. inwardly inclined openings 33, 34 constituting outlets for chamber 32. There is provided in body part l3, lengthwise of the latter a pair of spaced oppositely disposed tortuous tubular conducting passages 35, 36 which are closed at their inner ends and open at their forward ends into combined discharge outlet and air intake provided by the tubular part I4. The passages 35, 36 forwardly of their closed ends permanently communicate with the outlets 33, 34 respectively for the chamber 32.

Formed integral with and of less length than that of the part 26, which forms the rear portion of uniform diameter of the valve chamber 32, is a series of inwardly extending spaced ribs 31 disposed lengthwise with respect to the valve chamber. The ribs 31 are of less length than and are flush with the inner edge of part 26.

Positioned against the shoulder 30 and against the inner end. of the ribs 31 is a combined valve seat forming and intake member 38 in the form of an annulus and which has its outer edge abut part 25.

Arranged within the annular groove provided by the shoulders 28, 29 and part 24 is a combined sealing and retaining element 39 in the form of a resilient annulus 40 which bears against the shoulder 29, part 24, the rear face of member 38 and retains the latter in position. The inner and outer diameters of annulus 49 are greater than that of member 38. When element 39 is in sealing and retaining position, it is mounted on and extends outwardly from the edge of the bottle neck 19.

Prior to the coupling or connecting the attachment tov the bottle neck, the threads of the latter, as well as the threads of the coupling 3| are coated with cementitious material 4| possessing a characteristic when set to secure the attachment and bottle neck together in a manner to prevent the separation of one from the other without breakage.

Arranged within the valve chamber 32 is a pair of superimposed valves 42, 43. Valve 42 is globular and valve 43 of disc-like form. Valve 42 constitutes a Weighting means for and seats on valve 43. Thelatter is formed of resilient material. The valve 43, when in body part I2, is surrounded by the ribs 31.

When the attachment is set up, two like oppositely disposed body part sections are provided corresponding to the sections shown in Figures 2 and 9. These sections are formed of a material which will permit of connecting them together by fusing, brazing or welding to form an integral body. Prior to connecting the sections together, the valves, member 38 and element 39 are positioned within the sections. The body part l3 has an uninterrupted smooth outer periphery.

The modification shown in Figure 10 will be of the same construction as the attachment shown in Figure 1, with this exception, that the modification indicated at 44 will be formed with a corrugated outer periphery.

If the bottle is tilted with respect to the horizontal to the right, the passage 35 constitutes a fluid discharge passage and the passage 36 provides a combined fluid discharge and air intake passage. If the attachment is tilted with respect to the horizontal to the left, then the passage 36 forms a fluid discharge passage and the passage 35 provides a combined fluid discharge and air intake.

The parts of the attachment are so arranged to provide for discharge of the contents of the bottle after the attachment is disposed at an angle with respect to the horizontal and as the attachment,when extending downwardly,is moved towards the vertical, the flow decreases and completely stops when the attachment assumes an inverted vertical position. It is thought that the preventing of discharge from the bottle, when the attachment is in an inverted position and vertically disposed, is due to an air-trap effect within the attachment. The tubular tortuous passages are of like form, oppositely disposed,

'ber.

having offset closed branches and so formed as to prevent the passage of a wire or other implement to hold valve 36 off of its seat to surreptitiously refill the bottle.

The attachment is for employment in connection with any form of container having a neck or an annular extended intake or filling mem- The term container is also meant to imply a bottle or a jug. The term neck is also meant to imply an annular extended intake or filling member.

What I claim is:

1. A non-refillable attachment for containers of the neck type comprising respectively a tubular structure provided with means to provide respectively an internally threaded annular coupler for connecting it to the neck of the container; an internal annular groove forwardly of the outer end of the coupling; an internal annular shoulder forwardly of the groove; a valve chamber having a closed forward end, an open rear end and a rear portion of uniform diameter merging into the free end of said shoulder; a pair of spaced oppositely disposed outlets for said chamber; an opening at its outer end for receiving a removable closure and providing when the closure is removed a fluid discharge outlet and an air intake; a pair of spaced tubular conducting passages having closed rear ends and their outer ends merging into said opening; said passages communicating forwardly of their closed ends with said outlets; and inwardly extending spaced ribs integral with that portion of uniform diameter of said chamber and constituting valve guides, a combined sealing and retaining element mounted in said groove and for seating on the neck of the container when the attachment is coupled to said neck, a combined valve seat forming and intake member for said chamber interposed between said shoulder and element, said element and said member being in the form of an annulus, a disclike valve mounted on said member and encompassed by said ribs, and a globular valve mounted on and constituting a weighting means for the said other valve.
